Effect of Replacing Skimmed Milk Powder with Fish Meal on Body Weight in Early Weaned Piglets

摘要

The present study revealed that age of weaning and dietary composition had non-significant influence on body weight at all the ages from birth to 12th week of age except at 8th week. Significantly highest body weight at 8th week of age was recorded in feed 2 ( 100% skimmed milk powder replaced by fidh meal ) weaned at 56 days (T_2/56- 7.83 kg.) which did not differ significantly from feed 1 (with 4% skimmed milk powder )weaned at 56 days (T_1/56 -7.54 kg) and feed 2 weaned at 35 days (T_2/35- 7.03kg). However,significantly lowest weight was found in feed 1 weaned at 35 days (T_1/35-6.6 kg ) which did not differ significantly from T _2/35 group. Upto 5th week of age almost similar weight was observed in all the 4 experimental groups. After 5th week, the highest weights were recorded in piglets weaned at 8th week. Similarly, feed 2 was superior than feed 2 was superior than feed 1 at all the ages.
